The trick here is that a component doesn
'
t need a complete XML description to be
initialized
just the members that are either different from the default values
defined in the C++ component class or those members that have been recently
modified.
For the previous XML snippet, the code would find the
TranformComponent
of the
Grid actor and call
VInit()
, which would save the new orientation of the actor.
The last function that modifies actors is simply one that destroys an actor given its
ID.
—
void DestroyActor( ActorId actorId )
{
g_pApp->m_pGame->VDestroyActor(actorId);
}
With all the accessor functions defined, it is time to create the DLL.
When you create a DLL, you usually want to expose functions to any consumer of
that DLL. This is done with the
_declspec
keyword in a C++ header file. Here
'
s
how this looks:
#include
“
Editor.h
”
#define DllExport _declspec(DLLexport)
// Editor Framework Functions
extern
DllExport int EditorMain(
int *instancePtrAddress,
int *hPrevInstancePtrAddress,
int *hWndPtrAddress,
“
C
”
